Figure 5 in Morphology of camouflage by encrustation in the spider crabs Schizophrys dahlak and Hyastenus hilgendorfi (Decapoda: Brachyura: Majoidea: Epialtidae) from the Suez Canal, Egypt

Figure 5. Hyastenus hilgendorfi. (a) Box with arrow indicates cuspdenticulate setae on the merus of 3rd pereiopod; (b) denticles distributed along shaft; (c) arrows indicate aristate setae; (d) setal shaft aristate, drastically tapers from base to tip, terminal part pointed with an acute angle. Inset: prickle-like denticles; (e) air-dried ribbed setae on rostrum; (f) critical-point-dried ribbed setae; (g) arrow indicates wide grooves of ridged setae bordered by long, narrow ridges running across setal shaft. Inset: spiny needle-like denticles; (h) frilled spatulate setae on the abdomen; (i) setal shaft heavily frilled starting from medial portion towards tip. High density of tuskshaped denticles.
